Clumps, groups, or aggregation of cockroaches are held together by _______________________
Each German cockroach capsule contains __________to ___________ eggs
Three body segments: head, thorax and abdomen
The lineage of animals with protostome development can next be divided into two groups. What trait distinguishes these two groups?
What group is the most successful of all the animals, and what characteristics led to this success?
Three pairs of legs and typically two pairs of wings
Three body parts (but fusion of parts is common) Head, thorax, abdomen (cephalothorax)
marine, segmented body with septa separating soma, seta that aids in locomotion
Mouthparts vary with diet (herbivores, carnivores, scavengers, etc.)Complete digestive system with foregut, midgut and hindgut
= includes looking for, handling, and actually eating food, can occupy more than 50% of a primates walking hours
Spatial distribution of their food resources also affects _____ = responsible for much dietary variation
= park infants in crooks to foragepark their infants and produce higher in fat and protein milk
Seasonal differences in diet and feeding = reflect primate adjustments to seasonal differences in available foods
Anterior prosoma contains the major sense organs and brain and bears all the appendagesPosterior opisthosoma contains reproductive organs, respiratory structures, etc.
Polychaetes are dioecious with external fertilization and indirect development (larval stage)Earthworms and leeches are simultaneous hermaphrodites with internal fertilization
Active polychaetes have leg-like parapodia which are used to crawlSedentary polychaetes often live within a secreted tube (protein/CaCO3)Earthworms use circular/longitudinal muscles to push through the soil with peristaltic movementLeeches may use musculature and suction cups
Brain and sensory organs located primarily at the anterior/posterior ends, Tentacles, ocelli, chemoreceptors
Hearing—tympanum/lyriform organs/sensory hairsChemical—antennae, etc.Touch—sensory hairs
Snails, slugs, etc. glide along on their muscular foot, aided by lubricating mucous
May be active carnivores/scavengers, ectoparasites or sedentary filter feedersComplete digestive system with specialized organs (crop, gizzard, stomach, etc.)
